In this regard the current research was conducted during 2013-14 at The University of Agriculture, Peshawar to evaluate the performance of F recombinant inbred lines (RILs) to generate more comprehensive information on inheritance 5:9 and association of some production traits. Thirty four F RILs and two check cultivars Atta Habib and Janbaz 5:9 were evaluated in 6x6 alpha lattice design with two replications. Significant differences among recombinant inbred lines indicated the presence of sufficient genetic variability as reflected form its wide range from 25.5 to 53.2 cm for flag leaf area, 156.0 to 172.0 days for physiological maturity, 84.8 to 121.9 cm for plant height, 2 2017500 to 3982500 for spikes ha , 33.0 to 72.0 for grains spike , 1.5 to 3.4 g for grain weight spike , 39.8 to 1 1 1 54.5 g for 1000-grain weight and 3745.6 to 6711.4 kg ha for grain yield. Higher magnitude of genetic variances 1 than environmental variances resulted in high heritability (>60%) for flag leaf area (72.8%), physiological maturity (75.1%), plant height (92.6%), spikes ha (60.9%), grains spike (70.01%), grain weight spike 1 1 1 (69.17%) and grain yield (70.4%) accompanied by high genetic advance (10.9, 5.3, 15.1, 9924470.5, 10.5, 0.5 and 1054.7, respectively). These results indicated the prevalence of additive gene action in the inheritance of these traits and hence, amenable for simple selection. Furthermore, the study showed that spikes ha , grains spike 1 1 and grain weight spike could be used as most reliable selection index for yield improvement in wheat since 1 they manifested notable contribution towards grain yield. Key words: Association Recombinant inbred lines Alpha lattice Genetic variability Production traits INTRODUCTION In self-pollinated crops like wheat, the principle Wheat, the “king of cereals” holds significant performance and high economic yield. Countless research importance among cereals and is the major cultivated work has been done to explore areas of wheat breeding cereal and most important staple food of Pakistan. It through genetic manipulation, still increasing population holds significant position in the cropping pattern of the in the country necessitate the breeders for additional country. Pakistan ranks 8 among top ten leading wheat breakthrough in this food crop. Hence, in this regard plant th producing countries in acreage [1]. In 2013-14, the average breeders assess the extent of transmissibility for yield national yield of Pakistan was 25.6 million tons with an and yield attributes from parents to offspring in order to average yield of 2797 kg ha from 9.09 million hectares, bring improvement in heritable characters. In addition, it 1 in which our province, Khyber Pakhtunkhwa contributes also ascertains breeding stratagem to be pursued while 1.13 million tons from 0.73 million hectares with an improving a population. The assessments of broad sense average yield 1550 kg ha [2]. Its share in gross domestic heritability facilitate in envisaging the behavior of 1 products (GDP) is about 2.2% and 10.3% in the total value succeeding generations by planning suitable selection added in agriculture. criteria and calculating the level of genetic gain breeding aims are to develop cultivars with consistence
